NitRATE  OF  SODA. 

The  nitrate  sold  in  this  State  in  1918  has  maintained  the  usual 
quahty  having  an  average  content  of  15.49  per  cent,  of  nitrogen. 

Seven  samples  were  analyzed  as  follows : 

10955.  Sold  by  Berkshire  Fertilizer  Co.,  Bridgeport.  Old

The  price  of  10955  is  not  a  current  price. 

The  market  price  of  nitrogen  in  this  form  during  the  year  has  ranged 
from  32  to  37  cents  and  even  higher. 

COTTON  SEED  MEAL. 

Only  56  samples  of  this  material  have  been  sent  for  analysis, 
a  smaller  number  than  in  any  other  recent  year.  Of  these  analyses 
only  those  which  failed  to  meet  the  claims  of  the  seller,  eleven  in 
number,  are  given  in  table,  page  127. 

*  Not  sampled  by  station  agent. 


126  CONNECTICUT   EXPERIMENT   STATION   BULLETIN   209. 

The  percentage  of  nitrogen  ranged  from  5.12  to  7.02,  the  average 
of  all  samples  being  5.98  per  cent.  The  average  cost  per  ton  of 
the  56  samples  was  $57.41  and  in  most  cases  represents  dehveries 
in  car  lots. 

Cotton  seed  meal  contains  about  2.9  per  cent,  of  phosphoric 
acid  and  1.9  per  cent,  of  potash.  If  these  are  valued  at  5  and 
30  cents  respectively, 

the  average  cost  of  nitrogen  in  cotton  seed  meal  in  1918  has  been  about 
36  cents  per  pound. 

The  average  figures  for   the  last  six  years  have  been:

Much  less  unmixed  cotton  seed  meal  has  been  used  as  a  fertilizer 
this  year  in  this  State.  The  reasons  are  several.  It  was  sold  on 
sight  draft  instead  of  arrival  draft  and  buyers  did  not  care  to 
assume  the  risk  of  over  charges  in  freight,  loss  from  rough  handling, 
etc. 

Shortage  of  labor  made  the  work  of  home  mixing  more  difficult 
and  led  many. to  use  only  factory  mixed  fertilizers. 

The  higher  price  and  lower  content  of  nitrogen  also  lessened 
the  demand  and  freight  congestion  made  deUveries  uncertain. 

The  steady  deterioration  in  the  quality  of  the  meal  is  evident 
from  the  figures  given  above.  It  may  be  explained  by  the  facts 
that  because  of  the  high  price  of  cotton,  the  seed  has  been  closely 
ginned  to  secure  aU  the  cotton  possible,  and  where  the  seed  is 
nearly  ''bald"  the  removal  of  the  hulls  is  not  so  complete  as  where 
there  is  considerable  fibre  left  on  them. 

It  is  also  stated  that  the  removal  of  oil  is  more  complete  where 
a  larger  amount  of  hull  is  left  with  the  meal  and,  finally,  there 
seems  to  be  a  tendency  to  reduce  meal  generally  to  a  basis  of 
36  per  cent,  of  protein  (5.76  per  cent,  nitrogen). 

At  the  time  of  writing,  early  December,  43  per  cent,  meal  is 
quoted  in  Kansas  City  at  $67.00  which,  with  the  usual  allowance 
for  phosphoric  acid  and  potash,  makes  nitrogen  cost  over  38

The  average  ton  price  of  these  five  samples  has  been  $54.90. 
Their  average  nitrogen  content  has  been  4.92. 

Allowing  5  cents  and  30  cents  per  pound  respectively  for  the  phosphoric 
acid  and  potash  in  them,  the  average  cost  of  nitrogen  has  been  not  far 
from  48  cents  per  pound,  the  most  expensive  form  of  nitrogen. 

The  castor  pomace  situation  is  as  follows:  The  castor  beans 
formerly  imported  from  India  have  all  gone  to  England,  the  castor 
oil  being  greatly  needed  for  the  lubrication  of  aeroplane  motors. 

There  has  been  a  considerable  production  of  castor  beans  in 
this  country  since  our  entry  into  war,  but  it  has  had  no  effect 
on  the  supply  of  pomace  in  New  England.

Of  the  twelve  samples  with  cash  prices  attached  9  are  guaranteed 
16  per  cent,  "available"  and  3  are  guaranteed  14  per  cent. 

The  average  cost  of  the  former  is  $26.33  and  of  the  latter  $27.00. 

On  this  basis  available  phosphoric  acid  in  the  higher  grade  has  cost 
about  7.9  cents  per  pound  and  in  the  lower  grade  9.4  cents.

The  samples  contained  25.74,  19.62  and  18.70  per  cent,  of  potash 
respectively. 

11295.  Sold  by  Olds  &  Whipple,  Hartford.  Stock  of  E.  P. 
Brewer,  Silver  Lane.  .  Cost  $6.00  per  unit  of  water-soluble  potash, 
equivalent  to  30  cents  per  pound  for  actual  potash.  It  contained 
24.66  per  cent,  of  potash. 

11448.  Sold  by  Olds  &  Whipple,  Hartford.  Stock  of  John

soluble  potash,  chiefly  in  form  of  muriate. 


132  CONNECTICUT   EXPERIMENT   STATION   BULLETIN   209. 

11055.  Alpha  Potash — ^Lime  Fertilizer.  Made  by  the  Alpha 
Portland  Cement  Co.,  Easton,  Pa.  Sampled  and  sent  by  the 
manufacturer.  It  contained  2.59  per  cent,  of  water-soluble 
potash,  27.32  per  cent,  of  lime  and  1.01  per  cent,  of  magnesia. 

It  is  quoted  by  the  manufacturer  at  $12.00  per  ton  in  bulk  or 
$15.00  in  bags.  At  the  latter  price  and  making  no  allowance  for 
lime,  potash  would  cost  at  the  works  28.9  cents  per  pound. 

The  Potash  Situation. 

Already  truck  crops  in  this  country  have  undoubtedly  suffered 
from  lack  of  potash  as  respects  their  yield  and  shipping  quahty. 
No  marked  reduction  of  our  staple  crops,  which  have  a  longer 
growth  period,  or  of  fruit  crops,  has  come  to  our  notice. 

That  this  lack  of  potash  will  continue  in  1919  is  beyond  question. 

Before  the  war  the  country  imported  about  230,000  tons  of 
actual  potash,  more  than  90  per  cent,  of  which  was  used  as  a 
fertilizer.  Our  annual  requirements  for  the  immediate  future 
are  estimated  at  250,000  tons. 

In  1917  the  total  domestic  production  was  estimated  at  32,573 
tons  from  the  following  sources: 

From  the  brines  of  western  "lakes" 20,652  tons 

kelp  on  the  Pacific  coast 3,572 

molasses  residues 2,846 

the  mineral  alunite 2,402 

all  other  sources 3,101 

32,573 

The  sources  most  promising  for  the  future  seem  to  be  the 
brines  and  the  dust  from  blast  furnaces  and  cement  kilns. 

The  data  here  given  are  taken  from  a  publication  of  the  U.  S. 
Bureau  of  Mines,  The  Potash  Situation,  by  A.  W.  Stockett. 

In  view  of  this  critical  situation,  attention  should  be  given  to 
the  careful  conservation  of  the  very  considerable  but  neglected 
sources  of  home  production.  These  have  been  discussed  in 
Bulletin  198  of  this  Station,  which  is  still  available  for  distribution. 

Some  of  the  potash  salts  hitherto  obtained  from  brines  have 
contained  considerable  amounts  of  boric  acid,  and  such  salts  have 
seriously  damaged  crops  to  which  they  were  appHed,  as  has  been 
shown  by  Conner,  of  Purdue  University,  and  others. 


TANKAGE.  133 

IV.    RAW  MATERIALS  CHIEFLY  VALUABLE  FOR 
NITROGEN  AND  PHOSPHORIC  ACID. 

FISH  MANURES. 

Nine  samples  of  fish  manures  have  been  examined.  "  Dry- 
fish  scrap  "  as  put  on  the  market  before  the  war  contained  quite 
imiformly  about  8.25  per  cent,  of  nitrogen  and  6,0  per  cent,  of 
phosphoric  acid.  The  analyses  here  given  show  from  7.8  to  9.71 
per  cent,  of  nitrogen,  while  phosphoric  acid  ranges  from  3.13  to 
14.32  per  cent.  Obviously  they  are  not  wholly  dried  fish  scrap, 
as  the  term  was  formerly  used,  and  four  of  them  are  decidedly 
inferior  to  it  in  composition  and  value.  These  last  may  contain 
fish  residues  with  or  without  some  foreign  material.  Not  more 
than  three  have  a  fairly  consistent  composition  for  dried  fish 
scrap. 

No.  11296,  sent  by  Spencer  Bros.,  Suffield,  was  damp  and 
sticky,  unfit  mechanically  to  use  in  a  drill.  We  understand  that 
evaporated  "soup"  from  the  tankage  manufacture  is  sometimes 
used  in  fertilizer  mixtures  and  is  apt  to  give  this  sticky  con- 
sistence.   For  analyses  see  pages  134  and  135. 

SLAUGHTER  HOUSE  TANKAGE. 
Of  the  eight  samples  described  in  the  table  10892  and  10889 
have  the  composition  of  ground  bone  rather  than  of  tankage. 
The  same  is  true  of  10601  although  it  was  stated  by  the  sender 
that  it  was  sold  for  "blood  tankage."  10891,  sold  by  the  Nitrate 
Agencies  Co.,  failed  to  meet  its  guaranty  in  nitrogen  and  greatly 
overran  that  of  phosphoric  acid.  It  is  probable  that  the  stock 
which  it  represented  was  wrongly  branded  or  mixed  with  other 
goods.     For  analyses  see  pages  134  and  135.

other. 

Regarding  Rogers  &  Hubbard  Co.'s  Strictly  pure  fine  bone,  the 
manufacturers  state  that,  owing  to  the  scarcity  of  raw  bone,  the 
brand  had  to  be  made  of  half  raw  and  half  steamed  bone,  but 
in  1919  the  goods  will  have  the  same  composition  as  formerly, 
made  of  raw  bone  and  guaranteed  to  contain  3.82  per  cent,  of 
nitrogen  and  24.70  of  phosphoric  acid.

The  average  per  cent,  of  nitrogen  in  all  the  samples  is  2.93,  of 
phosphoric  acid  25.62,  and  the  average  price  is  $50.76. 

Allowing  five  or  six  cents  per  pound  for  phosphoric  acid,  the 
average  cost  of  nitrogen  has  been  between  34  and  44  cents  per 
pound. 


138  CONNECTICUT   EXPERIMENT   STATION   BULLETIN    209. 

V.    MIXED  FERTILIZERS. 

NITROGENOUS  SUPERPHOSPHATES. 

The  following  tables  include  analyses  of  263  samples  taken  by 
the  Station  Agent  and  4  taken  by  others.  Of  those  sampled 
by  the  Station  Agent  109  were  guaranteed  to  contain  potash. 

Regarding  Guaranties. 

Of  the  brands  containing  potash  29  failed  in  one  or  more  respects 
to  meet  their  guaranties.  Of  the  154  brands  which  did  not  con- 
tain potash,  34  failed  to  meet  the  guaranty  either  in  nitrogen  or 
in  "available"  phosphoric  acid.  Of  all  the  nitrogenous  super- 
phosphates examined  about  24  per  cent,  did  not  meet  their  guaran- 
ties in  all  particulars. 

In  most  cases  a  deficiency  in  one  ingredient  was  made  up 
in  money  value  by  an  overrun  in  the  others. 

In  the  following  cases,  however,  this  deficiency  was  not  made 
good.  Reckoning  nitrogen  and  potash  each  at  30  cents  per  pound 
and  "available"  phosphoric  acid  at  6  cents,  the  deficiencies  in 
money  value  of  more  than  one  dollar  per  ton  were :

Regarding   the   Quality   of    Plant   Food   in    Nitrogenous 
Superphosphates. 

The  potash  given  in  the  analyses  is  all  soluble  in  water  and 
readily  available  to  crops. 

The  same  is  true  of  the  "soluble"  phosphoric  acid.  The  "citrate- 
soluble"  phosphoric  acid,  which  with  the  water-soluble  is  called 
"available"  in  trade  usage,  is  doubtless  more  readily  available  to 
crops  than  the  citrate-insoluble,  but  there  are  probably  considerable 
differences  in  the  agricultural  value  of  citrate-soluble  phosphoric 
acid  coming  from  different  sources  or  materials.  The  same  is_true 


NITROGENOUS    SUPERPHOSPHATES.  139 

of  insoluble  phosphoric  acid.  Thus,  the  insoluble  phosphoric  acid 
of  bone  is  more  quickly  available  to  crops  than  that  of  phosphate 
rock  or  apatite. 

Considering  phosphoric  acid  alone,  it  is  safest  to  buy  those 
mixed  fertilizers  in  which  the  proportion  of  insoluble  phosphoric 
acid  is  smallest. 

Regarding  the  nitrogen  in  mixed  fertilizers,  the  availability  of 
the  portion  wliich  is  in  the  form  of  nitrate  or  ammonia  is  well 
understood. 

The  organic  nitrogen  of  mixed  fertilizers  comes  from  a  great 
number  of  materials  differing  widely  in  their  availability.  A 
method  of  measuring  approximately  their  availability  to  crops  by 
their  solubility  in  chemical  reagents,  has  been  devised  and  its 
value  has  been  checked  by  vegetation  tests. 

The  method  has  been  sufficiently  discussed  in  previous  reports. 
Only  its  application  to  the  tabulated  analyses  nded  be  noticed  here. 

The  organic  nitrogen  is  separated  into  the  water-soluble  and 
water-insoluble.    The  water-soluble  may  be  considered  available. 

The  water-insoluble  nitrogen  is  tested  for  solubility  in  a  defi- 
nitely prepared  potassium  permanganate  solution.  If  less  than 
50  per  cent,  is  soluble  by  the  alkaline  treatment  and  less  than  80 
per  cent,  by  the  neutral  treatment,  the  water-insoluble  organic 
nitrogen  is  considered  inferior  in  quality.  In  the  following  table 
are  given  those  analyses  in  which  the  water-insoluble  nitrogen  was 
judged  inferior  by  both  of  the  methods  and  in  which,  deducting 
the  insoluble,  inactive  nitrogen  from  the  nitrogen  found,  that  re- 
maining did  not  meet  the  nitrogen  guaranty. 

Analyses  Requiring  Special  Notice. 

10732.  Bowker's  Complete.  The  manufacturer's  chemist 
found  2.75  per  cent,  of  potash,  whereas  our  report  shows  2.36 
per  cent. 

11025.  Apothecaries  Hall  Co.'s  Victor  Tobacco  Special  with 
Cotton  Seed  Meal  Base.  As  this  sample  failed  to  meet  the  guar- 
anty, a  second  sample,  11175,  was  drawn  at  the  manufacturer's 
request,  which  fully  met  the  guaranty. 

10775.  Berkshire  Fertilizer  Co.'s  Root  FertiHzer.  The  manu- 
facturer advises  that  the  goods  should  show  between  3  and  4 
per  cent,  of  water-soluble  phosphoric  acid,  instead  of  only  1.12 
as  is  reported  in  the  table.

NITROGENOUS    SUPERPHOSPHATES.  141 

10876,  International  Agricultural  Corporation's  Buffalo  To- 
bacco Grower  contained  less  nitrogen  and  phosphoric  acid  than 
was  guaranteed.  Another  sample  was  drawn  at  the  manufac- 
turer's request,  11133,  which  met  the  guaranty. 

10819,  Royster  Guano  Co.'s  Overland  Top  Dresser  showed  a 
considerable  deficiency  of  nitrogen  but  nearly  double  the  amount 
of  phosphoric  acid  which  was  guaranteed.  A  second  sample, 
11132,  drawn  from  another  lot  at  the  manufacturer's  request, 
contained  less  nitrogen  than  the  former  and  less  than  half  as  much 
phosphoric  acid.  It  is  doubtful  if  either  sample  represents  the 
average  composition  of  this  brand. 

10791,  Royster  Guano  Co.'s  Perfecto  Tobacco  Manure,  con- 
tained 0.3  per  cent,  less  nitrogen  than  was  guaranteed.  A  second 
sample,  11123,  drawn  at  the  manufacturer's  request  from  another 
lot,  fully  met  the  guaranty. 

Regarding  the  Prices  of  Mixed  Fertilizers. 

The  prices  given  in  the  table  are  those  named  by  the  dealer  as 
cash  retail  ton  prices. 

The  price  of  a  given  brand  wiU  be  regulated,  not  only  by  its 
cost  to  the  retailer,  but  also  by  his  expenses  for  freight,  storage 
and  other  overhead  charges  and  by  his  margin  of  profit.  This 
however  does  not,  we  believe,  vitiate  a  comparison  of  average 
cost  to  the  farmer  for  the  purpose  of  this  discussion. 

There  are  a  considerable  number  of  brands  which  have  the 
same  guaranties  and  a  like  composition.  Thus,  we  have  22  brands 
in  each  of  which  3.29  per  cent,  of  nitrogen  and  10  per  cent,  of 
"available"  phosphoric  acid  are  guaranteed.  There  are  9  brands 
in  which  the  same  amount  of  nitrogen,  a  Httle  less  phosphoric 
acid,  and  1  per  cent,  of  potash  are  guaranteed. 

The  analyses  of  each  of  these  different  groups  have  been  aver- 
aged with  the  prices,  rejecting  those  in  which  the  prices  were  very- 
far  from  the  average.  As  is  justified  by  the  figures  previously 
given  in  this  report,  the  phosphoric  acid  has  been  given  a  value 
of  8  cents  and  potash  of  30  cents  per  pound,  and  with  this  allow- 
ance the  cost  of  the  nitrogen  in  the  different  groups  has  been 
calculated.     The  following  table  gives  the  results :

The  table  is  worth  careful  study  by  prospective  purchasers. 
It  shows  quite  conclusively  that  the  buyer  of  brands  with  only 
0.82  per  cent,  of  nitrogen  in  them  has  paid  not  quite  double  as 
much  for  nitrogen  as  he  would  pay  if  he  had  bought  goods  with 
a  higher  guaranty  of  nitrogen  and  at  a  higher  price.  He  would 
get  his  nitrogen  cheapest  if  he  bought  with  a  guaranty  of  at 
least  2.47  per  cent,  nitrogen. 

The  buyer  would  save  money  by  pa3dng  $50.85  for  a  3.29 
nitrogen  brand,  instead  of  paying  $15.00  a  ton  less  for  0.82  per 
cent,  nitrogen  goods.  It  was  better  buying  to  pay  $64  for  a  5-7-1 
formula  than  to  pay  $47  for  a  2.5-10-1  formula. 

The  reason  is  quite  simple.  It  costs  as  much  labor  and  material 
to  mix,  bag,  ship  and  sell  a  low-grade  fertihzer  as  it  does  to  prepare 
high-grade  goods,  and  they  are  practically  ahke  on  every  ton, 
whether  of  high  or  low  grade;  therefore,  they  make  the  cost 
of  plant  food  higher  in  those  goods  in  which  the  amount  of  plant 
food  is  relatively  smaU. 

For  example,  suppose  a  ton  of  fertilizer  (A)  contains  40  pounds. 
(2  per  cent.)  of  nitrogen,  and  another  (B)  contains  80  pounds 
(4  per  cent.)  of  nitrogen,  and  both  contain  equal  amounts  of 
phosphoric  acid  and  potash.  The  nitrogen  in  each  costs  the 
manufacturer  30  cents  per  pound,  and  let  us  assume  that  the 
other  plant  food  cost  $12.  The  "overhead  charges"  for  costs  and 
profits  of  manufacturer  and  sale  will  be  alike  in  each  case,  which 
we  wUl  assume  to  be  $12  also.

In  A,  124  worth  of  plant  food  costs  $36.  In  B,  $36  worth  costs 
^48.  Hence  in  A,  $1  worth  of  plant  food  costs  ff,  or  $1.50, 
and  in  B  If,  or  $1.33. 

These  "overhead  charges"  have  never  been  so  great  as  now. 
The  Station  has  always  advised  the  buying  of  high-grade  goods, 
but  at  present  it  is  imperative. 

There  is  nothing  in  the  argument  that  if  one  wants  to  use  only 
a  small  amount  of  nitrogen  (perhaps  on  oats,  for  example)  he 
should  buy  a  formula  containing  a  small  amount  of  nitrogen. 
Many  farmers  need  to  get  away  from  the  idea  of  putting  on  so 
many  pounds  (or  bags!)  of  fertilizer  to  th§  acre,  and  to  figure 
only  on  the  number  of  pounds  of  fertilizer  ingredients  which  their 
land  or  crops  need.

10726.  Sheep  Manure.  Brand  unknown.  Sampled  and  sent 
by  M.  H.  Pratt,  Hartford. 

11126,  from  the  Armour  Fertilizer  Works,  failed  to  meet  its 
guaranty  in  potash  while  the  amounts  of  nitrogen  and  phosphoric 
acid  considerably  overran  the  guaranteed  percentages.  At  the 
request  of  the  Armour  Works  a  second  sample  was  drawn  from  a 
different  lot,  11217,  which  fully  met  the  guaranty.  Sheep  manure 
cannot  be  expected  to  have  a  very  uniform  composition.  Thus, 
in  the  35  samples  tested  here  in  the  last  seven  years,  nitrogen  has 
ranged  from  1.0  per  cent,  to  2.74,  phosphoric  acid  from  0.83  to 
2.99,  and  water-soluble  potash  from  0.74  to  4.39  per  cent.  The 
average  of  all  these  analyses  is

11363  and  11350,  sent  by  S.  D.  Woodruff  &  Sons,  and  10726,

Obviously,  such  stuff  is  unfit  for  transportation  from  the  West 
to  Connecticut. 

While  sheep  manure  may  be  used  in  some  cases  in  place  of  horse 
manure,  in  greenhouse  work  and  on  small  lawns,  it  cannot  profit- 
ably be  used  in  farm  practice,  at  any  such  prices  as  are  charged  at 
present.

ASHES. 

Twenty-one  samples  of  wood  or  other  ashes  have  been  analyzed 
and  are  included  in  table,  page  165. 

9699  is  ashes  from  brass  works  sent  to  determine  their  agricul- 
tural value. 

9750  is  ashes  from  witch  hazel  brush  which  had  been  extracted 
in  a  witch  hazel  factory  and  then  burned  under  the  boilers. 

9749  and  11356  are  from  the  same  factory,  but  are  mixtures  of 
wood  and  coal  ashes. 

11199  and  10595  were  sent  to  determine  their  quality,  before 
purchase. 

10678  and  10677  probably  do  not  represent  material  offered 
for  sale  but  were  sent  with  inquiry  as  to  their  value. 

Only  the  following  samples  were  drawn  by  the  sampling  agent 
of  the  Station— 11139,  11054,  9750,  9749,  10615,  10861,  10897. 
Of  these  only  three,  9750,  10615  and  10897,  can  be  classed  as 
wood  ashes  of  fair  quality.  A  number  of  samples  sent  by  indi- 
viduals are  also  of  good  quality. 

If  we  reckon  lime  as  worth  50  cents  per  100  lbs.  and  phosphoric 
acid  at  6  cents,  the  water-soluble  potash  in  1G861  cost  about  35.6 
cents  per  pound  which  at  present  potash  quotations  is  not  ex- 
traordinarily high.

mouth  of  Oyster  River,  in  Branford.  It  was  asked  whether  the 
material  had  sufficient  agricultural  value  to  make  it  worth  handling. 
It  contained  54.11  per  cent,  of  water  and  41.02  per  cent,  of  mineral 
matter,  0.16  of  nitrogen  and  0.08  of  phosphoric  acid.  Obviously, 
material  like  this  which  contains  95  per  cent,  of  valueless  material 
cannot  be  profitably  handled. 

10841.  Alphano  Humus.  Sent  by  Edith  L.  Gilbert,  Kent, 
asking  if  it  is  as  advertised  in  Ross  Brothers  Catalogue,  a  copy  of 
which  was  sent  with  it. 

It  is  there  stated  to  be  "a  perfectly  balanced  soil  ration  that 
unfailingly  produces  immediate  and  long  enduring  fertility." 

"The  potash  it  contains  alone  is  worth  the  price."  The  price 
quoted  is  $20.00  per  ton. 


168  CONNECTICUT   EXPERIMENT   STATION   BULLETIN    209. 

It  contained  2.21  per  cent,  of  nitrogen,  1.16  of  phosphoric  acid 
and  0.08  per  cent,  of  potash. 

At  current  prices  "the  potash  it  contains  alone  is  worth"  about 
56  cents. 

In  respect  of  the  claim  as  to  potash  it  is,  therefore,  not  at  all 
as  advertised  by  the  seller.  His  claim  may  not,  however,  be  the 
same  as  that  of  the  manufacturer. 

10609  is  a  mixture  of  hen  manure  and  acid  phosphate,  sent  by 
W.  N.  Peck,  Mt.  Carmel.

had  been  exhausted  in  the  preparation  of  caffein,  sent  by  J.  Carle 
&  Sons,  153  Water  St.,  New  York.,  contained  about  50  per  cent,  of 
water.  It  also  contained  1.16  per  cent,  of  nitrogen,  0.26  phosphoric 
acid  and  0.31  per  cent,  of  total  potash. 

10003.  Copper  in  Horse  Manure.  Horse  manure  sent  by 
C.  M.  Jarvis,  Berlin,  who  reported  that  it  did  not  heat  readily. 
Sawdust  had  been  used  for  litter  in  the  stable  from  which  the 
manure  was  bought.  Copper  was  found  in  the  manure  which 
suggested  that  the  stable  had  used  for  bedding  sawdust  from  a 
factory  where  brass  parts  were  cleaned  by  mixing  sawdust  with 
them  in  a  tumbling  barrel. 

9747.  "Potash  from  Feldspar."  Feldspar  treated  in  a  furnace 
with  magnesian  limestone,  coal  dust  and  peat. 

It  contained  0.20  per  cent,  of  nitrogen  and  0.21  per  cent,  of 
potash  soluble  in  acid.  The  treatment  has  obviously  been  of  no 
marked  effect  in  making  the  potash  solilble.

OTHER  MISCELLANEOUS  SAMPLES. 

Fifty  samples  of  soil  have  been  tested  for  lime  requirement,  and 
ten  samples  of  various  materials  which  seem  to  have  no  general 
interest  are  not  further  noticed  in  this  report. 


REGARDING  THE  CHEMICAL  ANALYSIS  OF  SOILS. 

The  Station  is  constantly  receiving  samples  of  soil,  ranging 
in  size  from  a  few  teaspoonsful  to  a  pint  or  more,  taken  from  a 
garden  or  a  particular  field.  The  senders  usually  ask  for  an 
analysis  which  will  show  what  elements  of  plant  food  are  deficient 
or  lacking  in  the  soil,  or  they  wish  to  know  what  crops  can  be 
most  successfully  grown  on  it.  Analyses  of  such  samples  cannot 
furnish  the  information  which  is  asked  for. 

Chemical  analysis  does  not  as  a  rule  show  with  definiteness  what 
a  particular  soil  needs  in  the  way  of  plant  food  to  make  it  pro- 
ductive. An  analysis  shows  the  kind  and  quantity  of  the  elements 
which  are  in  a  soil,  but  cannot  show  what  elements  and  how  much 
of  them  are  readily  available  to  crops.  It  is  just  this  information, 
however,  which  we  need. 

With  the  rarest  exceptions,  our  soils  contain  every  element  of 
plant  food  and  in  amount  sufficient  to  produce  many  crops. 
Sometimes  this  food  is  not  in  sufficiently  available  form,  but  more 
often,  other  conditions  prevent  the  crop  from  utihzing  it.  There 
may,  moreover,  be  sufficient  available  plant  food  for  some  crops 
and  not  enough  for  others. 

p^  Experience  teaches  that  the  mechanical  condition  of  the  soil,  its 
water-supply  and  water-holding  capacity,  its  drainage,  temperature 


170  CONNECTICUT   EXPERIMENT   STATION   BULLETIN    209. 

and  aeration  more  largely  affect  the  success  of  a  crop  than  the  chemicals 
or  fertilizers  added  at  planting  time. 

The  good  effects  of  stable  manure,  which  are  out  of  all  proportion 
to  the  amount  of  plant  food  in  it,  are  due  in  part  to  its  effect  on 
the  other  factors  of  fertility  which  have  just  been  named. 

If  a  soil  is  not  sufficiently  underdrained,  if  its  mechanical  con- 
dition is  either  too  open  or  too  close,  or  if  it  is  not  adapted  to  the 
particular  crop  which  is  being  raised  upon  it,  then  it  will  not  yield 
satisfactorily,  no  matter  what  fertilizers  are  applied  to  it.  But 
on  all  these  points  a  chemical  analysis  gives  no  information. 

The  trouble  with  many  soils  which  give  unsatisfactory  returns 
being  their  physical  condition  rather  than  their  chemical  com- 
position, it  is  as  hopeless  to  search  for  the  trouble  by  chemical 
analysis  as  it  would  be  to  try  to  determine  why  a  man  was  unwell 
by  a  chemical  analysis  of  a  part  of  his  body.  If  a  soil  is  not  sour, 
if  it  has  the  right  texture,  if  it  contains  sufficient  water  and  is  not 
exposed  to  drought,  if  the  weather  conditions  are  favorable  and 
the  tillage  is  properly  managed,  then  in  most  cases  here  in  Con- 
necticut fertihzers  will  give  an  increased  yield,  but  if  the  conditions 
just  mentioned  are  unfavorable,  no  amount  of  fertilizer  will 
increase  the  crop. 

The  first  thing  to  consider,  if  a  soil  is  unproductive,  is  the  water 
supply,  which  may  be  improved  by  irrigation,  by  thorough  and 
intelligent  tillage,  and  also  by  the  increase  of  humus,  which  is  to 
be  secured  from  manure  or  by  green  manuring.  Next,  the  probable 
need  of  lime  should  be  regarded,  and  with  it  should  always  go 
more  attention  to  increase  of  humus. 

When  all  other  factors  of  fertility  have  been  made  as  favorable 
as  possible,  then  and  not  till  then  should  the  question  of  the  use 
of  chemical  fertilizers  be  considered. 

Whether  a  soil  is  relatively  deficient  in  quickly  available  potash, 
nitrogen,  or  other  element  of  plant  food,  can  best  be  determined 
by  actual  experiments  made  with  the  different  forms  of  plant 
food  on  the  land  itself.  Regarding  such  experiments  this  Station 
is  prepared  to  offer  suggestions  to  any  who  are  wilhng  to  undertake 
them.  This  deficiency  in  available  plant  food  cannot  be  determined 
by  any  chemical  laboratory  tests  at  present  known.
